ASH SIFTER.

Application led December 30, 1926. Serial No. 158,093.

The object yof vthis invention is to provide an improved ash sitter that can be readily mounted on :an ash can so `that the'ashes when si'fted -droip directly into the ash can while vvthe .piecesof unburned coal and large .clinkers rollout at ythe end of the ash sitter and into a bucket attached fto the ash sifter yon the Voutside ofthe ash ca This .and other' lobjects of this invention will be vfully illustrated in the drawing, described in fthe ,specification and pointed out in :the claims at the `end thereof.

lin :the accompanying drawing:

Figure l is a partial perspective and see-. Y tional View ofthe impro-ved ash sitter and upper portion .of .an rash vcan oir-which the ash sittter is imouirted.

Figure 2 is a detail perspective View of the removable.siftialgscreen of .the ash sifter.

Y.Figure 3 is ;a detail perspective view of the v removable hopper of the ash sifter.

In the several figures of the drawing like reference numeral-s indicate like parts.

Theash .sifter forming the subject matter ,of my present invention is cof a type that yca-n".be readily mounted on an ash can and operated thereon s0 that the ashes sifted will drop directly into the Vcan while the unburned ,particles of coal will roll out of the yash sift-er into -a bucket attached to the side .of the ash sitter on the outside of the ash can.

As illustrated in .the drawing the ash sitter has for its base a flanged cover 1Y which telescopes over the ash can to firmly support :the ash vs-i'f-ter thereon. In the center of the flanged-.cover 1 is provided ka rectangular opening 2 on the two sides and one end of which are anchored .suitable walls forming part of the casing 1A in which the sifting screen i3 Vis mounted. All but a small portion of the upper edge of each of the side walls is Yangular and between these angular edges of the side wall is supported the cover plater 4. This leaves a rectangular opening 5 1n the top of the casing` at the high end thereof in which the hopper 6 is supported. At the opposite or low end, the casing 1A forms a rectangular' nozzle 7 which over-hangs the cover base 1 and is provided with a hook 8 on which the bucket 9 may be suspended so as to be located below the nozzle 7 and receive the particles of coal or the larger clinkers that roll over the screen of the ash sifter and do not drop into the ash can.

As above pointed out the vscreen 3 of the ash sifter is mounted within the casing lccated abovc the rectangular openi-ngQ in the cover base 1. This screen 1s oblong and .is surrounded on the two sides and at one end by the flange 10. Reinforcing bars 11 and 12 are located on the under side of the screen 3 and are attached to the flange 10 to suitably support thekscreen at intervals .of its length.

To the closed end ofthe screen is 4attached the handle 13 which extends rearwardly yof the flange surrounding the screen and passes thru the horizontal slot 14 provided in the vertical end wall of the housing 1A surrounding vthe screen. ln the open end vof the screen a flange 15 is attached yto .it and extends beyond it and in this 'liange is provided a hole 1G whichisadapted to register with a corresponding holev 17 provided in the bottom of the nozzle end 7 of the casing 14 surrounding the screen 3. A cotter pin 18 or other suitable pivot pin is inserted thru the holes 16 and 17 thus pivoting the lower end ofthe screen into the nozzle end 7 forming part of ,thev casing surrounding the screen. The screen 3 is thus suspended at both ends within its casing. The casing 1^; in which `the screen is suspended is considerably wider' than the width of the screenwso that the screen may be moved laterally within it. As the lower end of the screen is pivotally fixed in the nozzle of the .casing it is only the upper end that can be moved sideways. The horizontal slot 111 thru which the handle 13 of the screen extends is therefore long enough to allow this handle to be moved lback and forth in order to give the screen an yoscil.lating motion on its pivot pin 18.

rlhe oscillating movement of the screen is limited by the lower end of the hopper 6 which is supported and extends into the Vcasing and projects between the flanges surrounding thescreen 8. lVhcn thc screen is oscillated, the inside of the flange 10 surrounding the screen 3 alternately makes contact with the outside of the opposing conical sides of the hopper 6 thus limiting the movement of the screen in either direction as well as slightly shakin g the lower end of the hopper so that the ashes contained therein are kept in motion and cannot settle in any particular' spot or bridge the whole of the inside of the hopper and prevent the ashes from dropping into the screen.

The hopper 6 is provided with a pair of holes 19 and 20 one on each side thereof 1,629,7ze c l ll Which holes are in line With Corresponding holes provided in the easing 1^ so thatl a pin can be inserted into thein and loeli the hop per in place in the easing. To remove the hopper these pins are removed and whe removed alloiv the hopper lo be lifted out of the ea'ing. A Cover 2l is hinged to the top of the hopper so that the hopper can be closed after the ashes have been dumped into it a 1d are being si'tred into the ish can. ln the front wall ot the hopper at the loWer end thereof is 'inovided the opening Q2. rthe size oilt this oieniug-i is regulated b v the gate 22:3 that located within the hopper and is suitably clamped in place to the inside ot the ilront wall thereof by means ot' a bolt 2l. ln the gate are pro-- vided a series of holes thru which the bolt 2e is adapted to pass and hold the gate at any desired elevation vfithin the hopper in order to regulate the size of the opening thru which the larger pieces olf elinlrers and the unburned eoal can pass and roll down over the screen into the bucket on the outside oli the ash sitter. Thus a large or small space may be provided between the screen lil and the top ot the opening in the Yfront ot the hopper depending on the ashes to he sited thru the ash sitter.

' ils above pointed out the hojper l is removable from the easing` and this also true ot the. screen 3. By simpl)T removing the pivot 'i8 the screen is 'released so that it can be moved forward until the handle 13 has been moved out ot' the slot le ritter which the screen can be pulled out olf the top ol" the. easing through the opening from -which the hopper has previouflj,r been reino-ved.

I claim:

l. 'In an ash sitter for ash Cans, the eoinbination ot a cover having an opening therein, an elongated reetai'igular easing having an opening at one end at the top thereof and an oi'iening at the opposite end thereof, a screen, a flange surrounding said soreen on two sides and one end thereof, a removable hopper adapted to engage into the opening in the top of said easing, and projecting between the [lange surrounding said screen, means for oscillating said screen, said flange oit' said of said screen being adapted to make oontaet with the outside ol said hopper to v1- brate said hopper at the end of each oso1llation.

ln an ash sitter for ash Cans, the eo1nbination of a Cover having an opening therein, an elongated rectangular' easing having an opening at one end at the top thereof and an opening at the opposite end thereof, a sere n, :i tl: j surroiniding said screen on two sides and one end thereoha removable hopper adapted to engage into the opening in the top ot `aid easing, and projecting beq tween the flange surrounding -said screen, ineens for o-seiliating said sereen, said flange ot said screen being adapte-d to maize contaet with the outside of said hopper to vibrate, said hopper at the end oit eaoh oscillation, an adir hopper a theifront wall thereol:I said gate being adapte-l 'o provide a large for small opening bei*l en said screen and the bottom the front Wall oit said hopper lo ailowlai or small particles ofeoal or elinkers to pass therethrough. .Y
